15 Claims.

My invention relates to an attachment for corrugating machines, suchasare usedin the manufacture of corrugated fiberboard. It has for one ofits objects the application of oil to the periphery of one or more ofthe fluted rolls employed in forming the corrugated component of thesheet.

Another object of my invention is to polish the surface of the roll orrolls and to remove therefrom adhering foreign particles, such as fiberdetached from the sheet of material operated upon.

In carrying out my invention, in its preferred form, I employ a rotarymember meshing with. the fluted roll to be oiled and cleaned, a portionof the periphery of said rotary member being formed of porous materialto which oil is supplied. Further, I impart to said rotary member areciprocating movement in the direction of the length of the fluted rollto polish its surface. I still further provide the rotary member withperipheral grooves in which fiber or other foreign matter on'thesurfacesof the rolls is collected due to the combined rotary and longitudinalmovements of the device.

In the accompanying drawings, which illustratean oiling and cleaningattachment made in accordance with my invention, Figure l is'a crosssection of a portion of a corrugating machine to which my attachment isapplied; Figure 2 is a plan view of the attachment; Figure 3 is alongitudinal section through the oiling roll and adjacent parts; Figure4 is a cross section ofthe oiling roll, showing a modification; Figurefiis an edge view of one of the oil conducting discs used in the modifiedform; and Figure 6 is an enlarged longitudinal section through a portionof the oiling roll, showing the application of one of the oil conductingdiscs.

"In Figure l, I have shown a portion of one type of con'ugating machineto which my atfrom which the finished product is produced This sheet,indicated by thebroken line A, is

led over the moistening roll 3 and thence over the top of roll 2 downbetween rolls l and 2 where the corrugations are formed. After passingaround the lower part of roll I, .where silicate is applied to the tipsof the corrugations by a transfer roll I, it is united to the liningsheet,

indicated by the broken line B, by the action of pressure roll 5. Thelining sheet is led to the roll 5 overs guide roll, 6, and the finishedproduct is led from between rolls I and 5 to discharge guide roll 'Icarried in brackets I on the frame of the machine.

In the form of corrugating machine shown, my attachment is mostconveniently mounted on a rockshaft 9 journaled in the brackets 8carrying the discharge guide roll. Keyed to the shaft 8 are arms l and Hforming the end members of the frame of my attachment. Arms i0 and H areconnected by bars i2 and I3 to form a frame which extends substantiallythroughout the length of the fluted roll I.

Mounted in the frame is the oiling roll, the i0 center of which isformed of a tubular member l4 closed at one end by plug having anextension journaled in the arm II and at the other by a plug is havingan extension journaled in the arm H. The tubular member forms the oil,15 reservoir of the device. Oil may be supplied to the reservoir througha central passage il in the plug 66, the outer end of the plug beingprovided with a threaded nipple I l for connection with an oilapplicator of the grease gun type. The to plug it is preferably providedwith a central passage IQ to permit the escape of air when the reservoiris filled. It will be understood that. the reservoir must not be fllledto a point above the openings ll and H9 or the oil will escape throughthese openings.

4 Mounted on the tubular member M are the oiling elements eachcomprising a central part 20 of felt or similar porous material and apair of end plates 2| of more rigid material, such as fiber. The objectof the end discs is to prevent spreading of the felt and to providesumcient rigidity of the oiling elements to permit the transmission ofmotion from them to the reciprocating mechanism hereinafter described.The peripheries of the oiling elements are fluted to correspond with thefluting of the roll to which the device is applied so as to makeintimate contact therewith when rotating in mesh therewith.

'The several oiling elements are held in align- 40 ment by being splinedto the tubular member M by means of a key 22 entering correspondingkey-ways in the elements. Each of the felt parts 20 may be formed of asingle block of material, as shown in Figure 2, but for convenience inmanufacture each part is preferably formed of a number of felt discswhich may be convenient- 1y stamped from sheet material. In Figure 3 Ihave shown each part 2| as formed of six such discs. The individualoiling elements are separated to form peripheral grooves between them byspacing discs 23. These spacers may be made of felt to convey oil alongthe outer faces of the fiber discs 2| but thisis not essential, and thespacers may be of non-porous material if desired. Oil is admitted to theporous portion of the oiling roll through openings 24 in the tubularmember I4 and thence passes to the periphery of the roll where it isapplied toth'd-surface of the corrugating roll I.. The plugs may beprovided with, Q

fiO

grooves 25 aligning with the openings 24 to permit oil to be suppliednearer the ends of the roll than would otherwise be possible.

In some cases it might be found advisable to provide means fordelivering oil to the porous material at points adjacent the peripheryof th oil roll. In such case I place between each pair of felt discs 20,or at least between some of them, a thin metal disc 26 having stampedtherein radial grooves 21, alternate grooves preferably projecting fromopposite sides of the disc. When such metal disc is positioned betweentwo of the felt discs 20, as shown in Figure 6, it will be imbeddedbetween the discs and the grooves 21 will provide radial oil passages 28to convey oil from the reservoir to points adjacent the periphery of thefelt discs.

Carried by or formed on the plug I5 is a gear wheel 29 meshing with anidler 30 loosely mounted on the cross bar l2. The idler 3|! meshes witha second idler 3| carried on a stud 32 mounted in the arm l0. Meshingwith the idler 3! is a gear 33 loosely mounted on the cross bar 13 andcarrying a cam 34. The groove of this cam engages with a roller 35 on ablock 36 rigidly mounted on the rock shaft 9. The rotary movement of theoiling roll is thus communicated through the gear train to the cam whichas it cooperates with a fixed roller must itself move,'imparting to theframe of the attachment a limited reciprocating movement in thedirection of the length of the corrugating roll.

In the operation of my device the oiling roll is held in mesh with thefiuting roll by its own weight as the frame is free to rotate on theaxis of the rock shaft 9. The oil-saturated felt of the center parts 20of the oiling elements are thus brought into intimate contact with theperiphery of the fluted roll to effectively lubricate its surface. Atthe same time the reciprocating motion of the oiling roll not onlypolishes the surface of the corrugating roll but causes any foreignmatter adhering to it to collect in the peripheral grooves between theindividual oiling elements. One end of the shaft 8 may be provided witha handle 31 by means of which the shaft may be rocked on its axis tolift the oiling roll from the corrugating roll to permit the removal ofdebris from the peripheral grooves of the former or to give access tothe surface of the latter.
